This research took Cidu railway station as an example. It applied eQUEST model (developed by U.S.A department of Energy) to simulate the hourly energy consumption under the infrastructure and air conditioner system of Cidu station, collecting the data of annual power consumption and transferring it as the norm of comparison. The research also simulated variation under different energy saving strategies, which include the increasing of indoor temperature, the introducing of outside air, the control of CO2, the improving of chiller efficiency, the parallel connection of two 300RT chillers, the parallel connection of 450 RT and 150RT chiller, and the reducing of illumination and compared the energy consumption between normal and energy saving models. As the result, the best energy conservation model can reduce 16.95% in building energy consumption and 29.53% in air conditioner energy consumption. Evaluating the individual saving model, the best one is to improve the chiller efficiency which can reduce 7.13% in building energy consumption and 15.04% in air conditioner energy consumption and the second one is to reduce the illumination of the station which can reduce 3.63% in building energy consumption and 1.68% in air conditioner energy consumption.
